Ainsworth, pointSIX Flooring

Featuring a patented tapered-edge that reduces swell, pointSIX OSB flooring from Ainsworth should not warp, sag or cup. It features tongue-and-groove profiling to lay flat, and the taper of its edge was based on research indicating that a 0.6mm tape depth is the most effective in reducing edge swell. It comes with a 25-year delamination warranty, and is available in a range of standard sixes and thicknesses. Wood is culled from SFI-compliant forests in Alberta, British Columbia, and Ontario, Canada, with the majority of it being northern aspen and a small portion in British Columbia being pine timber killed by the mountain pine beetle. ainsworthengineered.com
